本文主要研究内容
作者张章(2019)在《高含水期薄互层状油藏储层精细刻画研究》一文中研究指出:PZ油田是渤海湾盆地唯一一个石油储量达到十亿吨级的特大型整装油田,是中国海上最大油田,渤海油田重要产量支撑。该油田是在渤南低凸起带基底隆起背景上发育起来,处于郯庐断裂带上,属于被断层复杂化的大型背斜构造,核心部位受气云区影响地震资料品质较差,构造存在多解性。主要含油层段是新近系馆陶组和明化镇组下段,纵向上砂泥间互发育,累计油层厚度大(平均108米),但较为分散,油层纵向跨度大(平均472米),具有典型的小层数量多、非均质性强的薄互层状油藏特点。长期采用一套层系强注合采水驱开发,整体已经进入高含水期,受构造复杂、薄互层油藏特点影响,诸多开发矛盾日益凸显。以油藏精细描述思路为指导,基于地震重处理资料和丰富的钻井资料,充分结合区域构造沉积背景等,从地层格架、构造解释、沉积体系等方面进行再认识,开展高含水期薄互层状油藏储层精细刻画研究,指导剩余油分布规律研究,为油田高效挖潜提出对应策略。(1)基于区域构造分析和高精度相干技术,结合油田丰富动静态资料,从不同期次和级次断裂系统入手分析,对气云区走滑断层及其伴生次级断层进行系统刻画,明确田北东向走滑断层为PZ油主控断层,并改变了PZ油田已沿用十五年的构造断裂模式认识。(2)以沉积物源为基础,综合各类沉积相标志特征进行沉积相再认识,通过对基准面旋回及其伴随的可容纳空间变化进行分析,结合沉积演化规律,重新构建PZ油田沉积体系认识,认为PZ油田新近系馆陶组为浅水辫状河三角洲沉积,改变了前人认为是河流相沉积的认识。(3)基于地震重处理资料,通过曲线重构技术提高井震岩性标定精度,在PZ油田实现了“基于井震结合的储层预测技术”进行砂层组级别储层展布预测,结合储层沉积模式进行单砂体刻画,进一步以“动态演化过程分析”为核心,开展砂体内部结构解剖研究,并通过多资料模型融合建模技术,实现了多级次三维地质模型精细化表征。本论文在构造特征精细解释、沉积体系再认识基础上,深入开展储层精细刻画和定量表征,对剩余油分布规律进行深入分析,明确高含水期薄互层油藏剩余油分布模式,并提出纵向细分开发、平面完善注采井网、水平井局部挖潜剩余油的高含水期薄互层油藏剩余油立体挖潜技术策略,应用和实践效果良好,PZ油田水驱开发效果得到明显改善。
